concept-store

The memory-mapped concept store.

A redb database holding one code system version's concepts, displays, designations, and property values, keyed by dense ordinal, that terminology operations read point-wise: $lookup and $validate-code resolve a code here without touching the graph. Built offline, opened read-only by a server. No specification governs the layout: it is this project's own design.

Where it sits

concept-store is one crate of FerroTERM, a pure-Rust FHIR terminology server for SNOMED CT, LOINC, and other clinical code systems. The crates are published so other projects can reuse them; the API is pre-1.0 and moves with the FerroTERM release train. Documentation: https://docs.rs/concept-store.
